and services, support national and international needs, and respond to emergencies.  Introducing our National Capability  Weather and climate is big science, requiring large numbers of observations and data, large scale software and large-scale compute and storage. Because of this, the UK requires

Climate change may lead to less frequent but bigger and more devastating hail storms, new research has shown.

hail is likely to become less common, except potentially for very large hail. Severe hail has a diameter of 2 cm, while a diameter of 5 cm or more is considered very large. Bigger hailstones cause more damage than smaller ones, and even a small increase in their size could outweigh any benefits

, providing detailed information to aid decision-making across the public sector and private industry. Enormously ambitious project Dr Jean Innes, CEO at The Alan Turing Institute, said: “This project aims to tackle the big hold-out problem in weather prediction – fast and accurate prediction of impactful

warm temperatures, making it a pleasant, albeit slightly cooler day.  Aidan McGivern, Met Office presenter and meteorologist, said: “Remarkably warm for the first morning of May, but a big temperature contrast by the afternoon as a cold front sinks south, bringing showers to Scotland and Northern

impact our lungs, and enter our blood stream, damaging our heart or brain. The more of these pollutants we breathe, the higher the risk of harm and the bigger impact it can have on our health. There are many causes of air pollution. Outdoor air pollution’s caused by: • vehicles (cars, vans, planes

, and it describes full moons that appear noticeably larger and brighter than usual. In fact, a supermoon can seem up to 14% bigger and 30% brighter than other full moons, making it a particularly striking sight in the night sky. It is worth noting that definitions of a supermoon can vary slightly within

amounts accurately, which can have a big impact on the accuracy of temperature and sunshine forecasts. Simon explained: “Once you get into the detail of forecasting specific cloud amounts in specific locations, it takes a certain amount of skill, from both weather models and meteorologists

in weather phenomena. These AI weather models can already compete with the current generation of NWP models and, for some applications, exceed their performance at a fraction of the computational cost.  Big tech companies including Google, Microsoft, Nvidia and Huawei have made significant advances

that high pressure will increasingly influence the UK’s weather as we move into early April, temperatures are likely to fluctuate, and colder air will never be far away. The bigger picture: jet stream and pressure patterns A key driver of the forecast over the coming days is the position of the jet stream
